Host computer virus control system and method for industrial control system

Abstract

The invention discloses a virus control and prevention system and method for a host of an industrial control system. The system and method aim at achieving the technical purpose of providing a virus control and prevention strategy of the industrial control system, wherein the host of the industrial control system can be prevented from being directly or indirectly subjected to virus library upgrading through the connection with the internet, and the transmission path of viruses through a mobile storage medium can be cut off. According to the embodiment of the invention, format authentication ofan anti-virus terminal management server is conducted on the mobile storage medium; the mobile storage medium is linked with a mobile storage medium authentication and updating device connected witha virus upgrading server, and automatic encryption write-in updating of a latest virus library is carried out; finally, the mobile storage medium in which the latest virus library is written is linkedwith the host of the industrial control system, wherein a virus control and prevention terminal is installed in the host and can conduct virus library updating and virus checking and killing on the host of the industrial control system according to the latest virus library in the mobile storage medium, and therefore the virus control and prevention are achieved.

Description

technical field [0001] The invention relates to the technical field of information security of industrial control systems, in particular to a host computer virus prevention system and method of an industrial control system. Background technique [0002] In recent years, the information security situation has become more and more urgent, and industrial control systems are gradually becoming the key target of hacker attacks. At the same time, there have been incidents where industrial control systems have been seriously affected by hacker attacks. Therefore, the virus prevention and control work in industrial control systems should be highly valued. . [0003] Some important industrial control systems, such as dispatching automation systems in the electric power industry, substation monitoring systems, etc., are all important national information systems. Such information systems need to be managed according to their importance levels. For important systems, it is necessary ...
